Ok...Got the extended battery the other day, and have gone through a couple of cycles with it. Charged it all night, then "bump charged" this morning. Gonna see how much time I can get out of it. Perfomance is set to Normal. My one obstacle is the horrible cell service here at my house. I'm starting to think that that is really the biggest consumer of power for me. Anyone have any experience with the Verizon network extender in their home? Thanks.
